St. Athanasius the Great 297-373
Now it is the opinion of some, that the Scriptures do not agree together, or that God, Who gave the commandment, is false. But there is no disagreement whatever, far from it, neither can the Father, Who is truth, lie; ‘for it is impossible that God should lie Heb. 6:18,’ as Paul affirms. But all these things are plain to those who rightly consider them, and to those who receive with faith the writings of the law. (Letter 19.3)
